UNITED STATES ISIDOR-E BIRGIJ, OF PHILADELPHIA,

PENNSYLVANIA, ASSIGNOR TO THE TRANSIT APPARATUS COMPANY, (LIMITED,) OF SAME PLACE.

STQRE-SERVlCE APPARATUS.

SPECIFICATION forming part of Letters Patent No. 325,383, dated September 1, 1885.

Application filed April 23, 1885. (No model.)

To all whom it may concern:

Be it known that I, ISIDORE BIRGE, a citizen of the United States, residing in the city and county of Philadelphia, in the State of Pennsylvania, have invented an Improvement in StoreService Apparatus, of which the following is a specification.

My invention relates in general to the class of storcservice apparatus in which the traveling carrier is a basket or other goods-receiver, suspended from the depending arm or hanger of a one or two wheeled truck, the wheel or wheels of which travel upon an elevated track composed of a single rail.

My present improvements relate specifically to the movable or switch rails of store-service tracks of the above class, and more especially to such switch-rails as operate in conjunction with a flaring guard of a character invented by me and patented to me in and by United States Letters Patent No. 300,198, issued June 10, 1884.

My invention, generally stated, consists in providing a switclrrail or a movable section of the rail of a track with a depending con nected or attached guard, adapted to steady the depending arm or hanger of a truck against undue oscillation or centrifugal throw during i-heperiod when the carrier is upon said switchrail.

In an application executed by me contemporaneously with this application, filed upon the same day, and designatet Case A, I have described what I term a hanger-rail, which is supported or suspended in fixed re lationship below the track to the outside of curved portions thereof. In this application, therefore, I lay no claim, broadly, to the provision of a guard device below a carrying track or portion thereof, but confine myself simply to the provision of a fixed depending guard applied to a movable switch-rail, and which, being a fixture with said switch-rail, has a common movement therewith.

Apparatus embodying my invention is represented in the accompanying drawings, and described in this specification.

In the drawings, Figures 1 and 2 are perspective views, respectively depicting a switchrail in-two positions,open and closed. Fig, 3

is a top plan view of the same with the switch open.

Similar letters of reference indicate corresponding parts.

In the drawings, A A are forked suspenders or bridges which support the rails. B is the main track. C is the branch track, and D the switch-rail, which is adapted to place the branch track in communication with the main track. The switch-rail may be of any preferred construction, and either be mounted for gravitative action under the weight of the carrier when upon it, be connected with gearing through which positive movement is imparted to it, or be otherwise applied or arranged, at will.

E is the depending guard with which the switch-rail is provided, and which may be either integral with the switch-rail or attached thereto as aseparate member, as shown. guard is of especial applicability to a switchrail, because the direction of the travel of the carrier being at switches changed, and the path being more or less curved, it is obvious thata greater or less degree of oscillation or centrifugal throw or movement is imparted to the depending arm of the carrier.

F is a flaring guard, of a general character set forth in my patent liereinbefore referred to, applied to the forked Suspender A but in the present instance carried below the level of the base of the main track or rail and, as to its under surface, to a position approximately abreast with the depending guard of the switchrail, so that said flaring guard forms not only a throat to guide the hanger of the truck, and, if necessary, to force said hanger to move the switch-rail, but also a device which co-operates with the switch-guard in preventing the oscillation of the hanger.

My guardis of special applicability to switch rails which are themselves curved; but it is equally useful with all switch-rails of the class herein referred to. Of course, if the branch track in the region of its approach to the switch-rail is curved, it is proper to apply to it the hanger-rail set forth in the application for patent hereinbefore referred to.

Having thus described my invention, I claim This extremity of the switch-rail and adapted to cooperate with the switch-guard in steadying the travel of the carrier from the switch-rail to the main track, substantially as set forth. 1 5

In testimony whereof I have hereunto signed my name this 28th day of March, A'. D. 1885.

ISIDORE BIRGE.
